Conservatories were originally invented by the Romans, who used them to look after exotic plants and fruits. (Conservato means to store and preserve, while ory means ‘a place for’.) Today around 1 in 5 households in Britain now have one, and they’ve evolved into structures with a far more diverse range of purposes – which goes some way to explaining why it’s becoming so popular to buy conservatories in Blackburn and Darwen.
